That just about brings our live coverage of the Australian Open to an end for today.

Thanks for joining us and see you tomorrow for the conclusion of the fourth-round ties.

Earlier today, American third seed Coco Gauff had to fight from a set down to beat Switzerland's Belinda Bencic and reach the quarter-finals in Melbourne.

Gauff will face 11th seed Paula Badosa after the Spaniard defeated Serbia's Olga Danilovic.

The pair join top seed and defending champion Aryna Sabalenka after the Belarusian breezed past Russian 17-year-old Mirra Andreeva in a 6-1 6-2 victory.

Sabalenka will play Russian Anastasia Pavlyuchenkova in the last-eight following her win over Croatia's Donna Vekic.

Already the fact that he has not down the on-court interview has got tongues wagging. If he skips his media as well, people will be thinking ‘what’s up’. It adds to the intrigue.

He could have said 'could you keep it to two questions and I’ll be off'. Then he didn’t need to sign so many autographs.

It’s a PR loss. There were some boos for Djokovic because the crowd wanted to hear from him.

So Novak Djokovic will play in a 15th Australian Open quarter-final after that straight sets win over Jiri Lehecka.

The Serb seventh seed will play Carlos Alcaraz in a mouthwatering tie after the Spanish third seed got past Jack Draper earlier today.

The Briton's last-16 tie ended in disappointment after he retired after going two sets down in the searing Melbourne heat.

The other men's quarter-final set up today will see German second seed Alexander Zverev face American 12th seed Tommy Paul.

I have got to say these on-court interviews tend to lose track a little bit with what’s going on. They end up getting players to sing and dance and do all sorts of things. I know it’s great for social media and stuff.

Clearly he did not want to talk tonight and have a discussion about Alcaraz and the match and losing two Wimbledon finals, because that is inevitably what Jim Courier would ask.

He may have swerved his on-court interview but Novak Djokovic did stop to talk to Eurosport. He said:

"I felt great. A couple of hiccups here and there, a loose game when I broke his serve in the third. I had some chances to break him but every time I had an opportunity he would serve big. Just very powerful and precise.

"Obviously [Lehecka is] a little bit of a different opponent compared to my last round but a few similarities – flat backhands and quite aggressive style. But I think I handed well the pressure moments and some moments at the end."

On being a perfectionist and hating making mistakes:

"Who doesn’t? We all try to handle it in our specific way. Sometimes I do it better, sometimes I work against myself. Only people who have been there at the highest level understand what you have to deal with. There is a lot on the plate and you have to weather the storm when you are feeling challenged."

On his coach Andy Murray looking nervous:

"I don’t notice that, pretty much he has the same poker face I have seen on the court for 30 years on the court, trust me. He’s someone that understands very well what kind of pressure moments, what kind of energy I have to deliver on the court when you are challenged by your opponent and all the other things.

"It's great to have so much energy from him."

I'm not sure why Novak Djokovic decided not to do his post-match on-court interview - perhaps it was linked to the distractions from the crowd on serve during that third set.

He's speaking to the TV broadcast media now and seems in good spirits, where a fan of 20 years has just given him a t-shirt with a 17-year-old Djokovic on the front.

Perhaps we will hear more from Djokovic during his post-match news conference later.

Novak Djokovic will play Spanish third seed Carlos Alcaraz in the quarter-finals by the way, what a matchup that is.

Novak Djokovic decides not to do the on-court interview - but does address the crowd before walking off-court:

"Thank you very much for being here tonight. I appreciate your presence and the support and I’ll see you next round."

Poor first couple of sets from Lehecka but he played well that last set. Novak had to start playing improved tennis.

Probably not still in the form he would like and he needs to be better in the next round.

Novak Djokovic slides and stretches to somehow guide a forehand across court which lands just inside the line - it's wonderful speed, agility and guile from the 37-year-old and that shot has got the crowd back on his side.

Jiri Lehecka is not put off as he comes through to hold, and Djokovic will now serve to stay in the third set.

Novak Djokovic double-faults before complaining to his coaching team.
